Question: 1 / 400

What does the prefix x10^9 represent?

mega

kilo

giga

The prefix x10^9 represents "giga." This prefix is part of the International System of Units (SI) and is used to denote a factor of one billion or 1,000,000,000. In scientific notation, "giga-" is commonly used in contexts such as gigabytes, where it indicates a billion bytes of data.

Understanding metric prefixes is important in many scientific and medical fields, as they help convey large quantities efficiently. For example, while "kilo-" denotes a factor of one thousand (10^3), and "mega-" denotes a factor of one million (10^6), "milli-" denotes a factor of one-thousandth (10^-3). This hierarchy highlights the specific scale associated with each prefix with "giga-" being a significant step larger than the others mentioned.
